WINDOW-OPERATING ivrEcHA'NIsM.`

Application med May 16, 1910. serial No. 561,778.

To all whom t may concern:

Be it known that I, ROBERT A. LACKEY, a"

of windows are automatically operated so as to be simultaneously openedand closed. rJihe invention has for one 5f its objects, the provision of a mechanism which shall be simple in construction, cheap to manufacture and easy to install, and which will open all of a series of windows to the same extent and will likewise close them all tightly at the same time without leaving some of the windows partially open.

Another object of the invention is the provision of a device of this character, which shall be efficient in its operation and which will utilize advantageously the force applied to it with the least degree of friotional resistance and strain upon the mechanism. y

Additionalcbjects and advantages of the invention will become apparent as itis better understood by reference to the following description when taken in connection with the accompanying .drawings illustrating a preferred embodiment thereof. Y

Referring to the drawings-Figure 1 is a plan view of a structure embodying my in vention, on line 1 1 of Fig. 2. Fi 2 is a front elevation of a portion thereo Fig. 3 is a section on the line 3 3 of Fig. 2. Referring to the drawings, 4 represents a portion of the wall of a building in which there are arranged a series of window sashes 5. The sashes are shown as pivotally mounted at or near their centers to swing about a horizontal axis; the upper portion 6 of the window jamb being located outside the' sash and the lower portion 7 located inside the sash to permit the bottom of the windows to swing outwardly and the top inwardly. .It will be understood, however, that the windows may be mounted in any other preferred manner, as forinstance by hinging them at the top so that the bottom may be swung outwardly by my improved operating mechanism, or by hinging `them either at the top and bottom or at one side so as to swing in a vertical plane.

to each section ofthe `wall between the ad- ]acent windows of the series, is a bracket or supporting block upon which `are mounted at 9, a air of pivotal members 10. As will be evident from Fig. 1, the brackets 8 project at either end a short distance beyond the edge of the wall section, and the pivotal members are mounted near the eX tremities of the brackets so as to be capable of swinging outwardly. on their pivots into window openings without striking against the'edges of the wall section.

`Each, window sash has secured thereto near each side, a pivot plate 11. A link 12 is pivoted at one end in said pivot plate and pivoted at the other end to the outer end of the adjacent pivotal member 10. The pivotal connections between the link 12 and the pivotal member 10, and the pivot plate 11, are` designed to afford sufficient play to permit the window sash to be swung outwardly and `upwardly about its pivotal bearing without cramping or binding the link 12.

A pair of operatingrods 13 and 14 eXtend `longitudinally of the series of windows and are supported so as to be capable of longitudinal movement in suitable bearings prothey are adapted to move longitudinally may be constructed to accommodate the particular shape of rods employed and permit them to slide freely therein. A plurality of collars 16 are adjustably secured upon each of the rods, said collars having laterally projecting portions `adapted to receive the ends of links 17 pivotally attached at their'other ends to the pivotal members 10. The upper operating rod13 is connected by every alternate link 117 with each of the pivotal members 10 disposed at the right of a window opening, viewing Figs. 1 and 2, while the lower operating member 14 is pivotally connected by means of the remaining links 17 with the pivotal members 10 mounted at the left of the window openings.l

yIt will be evident from the above construction, that longitudinal movement of the operating rod 18 to the left viewing Fig. 1, will swing the pivotal members attached at `the right lside of the window sashes upon their pivots into the dotted line position p shown in Fig. 1, and that simultaneous lon# gtudinal movemeiitor1 the operating` 14 connecting the pivotal members to the op-.

erating rods by means of links, as described, the pivotal members are enabled to swing through nearly an arc of 180O thereby nearly doubling the range of movement of the windows ,over constructions `which pivotally connect the operating rods directly to the pivotal members, thereby vlimiting the movement of the pivotal members'between positions perpendicular to and parallel with the window or to an arc of 90".v Simultaneous movementv of the operating rods in opposite directions, is accomplished rby connecting the rods togetherat both ends to any suitable type of operating mechanism.y

l have shown for the purposes of illustration merely, one ferm of operating mechanisin comprising` a chain 18 passed over a sheave 19 and attached at one end to the operating rod 13 and at its other end to the operating rod 111'. rThe sheave 19 may be rotated by any preferred form of operating mechanism to simultaneously move the operating rods longitudinally in opposite directions. f

ySimultaneous swinging movement or' the pivotal members 10, serves, through the intermediary of the connecting links 12, to operate both sides of the windows'simultaneously and "equally, thereby overcoming any tendency of wide windowsto stick, such as usually exists in connection with operatingv mechanisms leaving but 'one point of attachment to windows of considerable width. For narrower windows, h owever, one point of connection may be found suilicient, in which instance but Ione o-perating rod would be employed and half of the connections could be dispensed with.l f

By connecting the operating rods to the windows in the mannerabove described, the greatest force is exerted upon the windows when they are practically closed, z'. c., the mechanism is capable of exerting the greatest amount of force upon the windows when the parts are in the position shown in full lines in Fig. 1 and since any opposition to the movement of the windows occasioned by sleet, snow or *sticking` of the windows, always occurs when the windows are in substantially closed position, the greatest eiiiciency of my mechanism is derived at the time 4when it is mostneeded. 1t will be evident also, that the farther outinto the lwindow openings the pivotal members 10 are swung during the-'opening operation, the more nearly the links 17 approach a perpendicular to the operatingrods, and that the nearer 'the links approach ythe perpendicular, assuming that the operating rods are moved at a constant'speed, the faster the outer ends of the pivotal members and consequently the windows, will be moved. This is a very desirable feature in window operating mechanisms for the reason that after the windows have been started from the frames but little resistance is oiifcred to their movement, and power which was very essential in starting the windows becomes a sec- 4ondary factor in importance to speed during the remainder of the movement. Myiinproved operating mechanism is so constructed that the power applied thereto, is utilized to the best advantage to exert the greatest force upon the windows in initiating the opening and completing the closing movements, and to move the windows at accelerated speed during the remaining portion of their movement. Another advantage of my construction resides in the fact that the weight of the windows when in open position, is distributed between the pivotal members 10 and the links 12, thus relieving the operating rods of a large part of the lateral thrust thereon occasioned by the -Weight of the open windows.

.While I have shown and described a pie- 'ferred embodiment of my invention, it will be apparent that various minor mechanical changes may be resorted to without departing from the spirit of the invention or sacrificing any of the material advantages thereof.
